ORIN had the opportunity to travel to Ft. Buchanan near San Juan, Puerto Rico to conduct an Enhanced Reductive Dechlorination injection (ERD). The project was designed to treat contaminated groundwater affected with chlorinated solvents. A […]

ORIN has completed work at a former gas station in western Nebraska utilizing in-situ chemical oxidation with vacuum extraction. A dual phase extraction system was previously in place, but was not sufficient in meeting the […]

ORIN had just traveled to southern Alabama to successfully reduce concentrations of benzene and naphthalene in groundwater utilizing in-situ chemical oxidation. The site is a former military base with a targeted treatment area of approximately […]

ORIN has completed the fifth and final planned injection event at a site in northwestern Wisconsin. Bedrock injection can be difficult to perform, given the many micro-fractures associated with the matrix. Manganese dioxide (MnO2), a […]

Objective
ORIN sought to compare the effectiveness of sodium permanganate and sodium persulfate treatment chemistries on TCE and PCE contaminated soil.
Methodology
Total oxidant demand testing for both persulfate and permanganate were performed with site soils. Oxidant consumption […]

ORIN completes first of three rounds of injection for pilot testing of extract and re-inject process to create an oxidizing barrier to intercept the groundwater plume. Project implantation is being conducted to test the treatment […]
